SPECIFICATION forming part of LettersPatent N0; 781,180, dated J'armary31, 1905.

i Application tied J'uiy 29, 1904. serial No. 218,651. A

To all whom it may concer-7e: l

Be itknown that I, CHARLEs C. BRABANT, a

citizen of the United States, residing at Al` 4are constructed withaview of cushioning such weight and lateral pull and thrust as are imposed upon them; and it consists in thepeculiar and advantageous hub ofvthe type mentioned, hereinafter described, and particularly pointed outin the claims appended.

In the accompanying drawings', forming metrical section of my.improved-hub with some of the parts in elevation. Fig. 2 1s a vsectiontaken in the plane indicated by the line 2 2 of Fig. 1`. Fig..3 is atransverse section taken in the plane indicated `by the line 3 3 of Fig.l looking toward the left, and Fig.

'A is a detail perspective view of one of the and also has three more orless circumferen# tial grooves c, OZ, and@ and a key-seat f intermediateof the grooves d ande, and B is the casing of my improved hub. The saidcasing 1s circular in cross-section andismade up of an outer section g,closed at its outer end and open and exteriorly threaded at its innerend and having spoke-sockets 7L on its f perimeter and one or morelongitudinal g'rooves c' in its inner side and an inner section Zscrewed on the inner end of the outer section and having a large centralopening lo.

C is an annulus, of felt or other suitable material, havi'ng a reducedinner portion snugly occupying the circumferential spacel between thecollars aand b of the axle, and D is a belvlows, of strong textile orother suitable masaid annulus C and bellows D will accommoi vof the mainsection.

datethemselves to and in no measure yinterfere with the movements of thehub-casing .with respect to the axle, it will be observed that they willpreclude the entry of dust, grit, and the like into the casing, andhence will materially prolong the usefulness of the working partscontained in the casing.

E is a boxing contained in the casing B and held thereto by longitudinalribs m, disposed in the groovesrl of the casing-section g.

. F is an annular shell arranged within the 1 boxing E and having one ormore circumferential grooves n in its perimeterand also hav.- ing lugs pextending inwardly or toward the centerpof the hub from its side edges.

Cr G are antifriction-balls arranged in the grooves n of the shell F andinterposed between the said'shell and theboxing E, so as to enable theboxing to bear on and turn around about the saidshell F with but aminimum Aaxle and having its free portion disposed against the innerside of the shell F. I prefer to provide the weight-sustaining spring atits inner end with a collar q,- which surrounds the axle A and has akey-seat r, designed in connection with the key-'seat f' of the axle toreceive a key s, which is retained in position by a collar t, screwed'ona threaded portion of theaxle, as best shown in Fig. l.

In addition to the weight-sustaining spring vH the hub comprises twosets of weight-sustaining sp'rings lettered I and J, respectively.vThese springsIand J are preferably provided with dovetail inner ends a,and are connected to the axle through the medium of blocks K L, whichloosely surround the axle and are designed to turn on antifriction-ballsM, arranged in the grooves c, CZ, and e. The blocks K and L respectivelycomprise a mainl section o, having dovetail grooves w in its perimeterto receive the dovetail ends ofl its springs and also having athreadedend and a cap-section y screwed on said threaded end The dovetail innerends of the springs I J are removably secured in the main sections oftheir respective blocks K L by the cap-sections y thereof. y

The weight-sustaining spring H by reason IOO of the interposition of itsouter portion or whirl between the lugs p of the shell F is enabled tohold the said shell against lateral "movement in the boxing E, and henceis cal-A culated to efficiently cushion such weight as is imposed uponthe middle of the hub-casing. Said springH is also adapted to assist theend series of springs I J in sustaining' such weight and shock and jaras are imposed on the end portions of the hub-casino'.

Interposed between the' ends of the collar q of the spring H and theinner ends of the spring-blocks K and L are the springs for cushioningand taking up shock and jar imposed on the hub incident to lateralthrust or pull. rIhe said springs, which are lettered N, are identicalin construction, and therefore a detailed description of the springshown in Fig. 4 will suiiice to impart an understanding of both. rIhesaid spring N, Fig. 4, is formed of a single piece of steel or othersuitable metal and comprises a body d, having a central aperture b,adapted to loosely receive the axle A, and curved arms c', extendinglaterally and inwardlyV from the ends of the body a'. The bodies of thetwo springs N are arranged to bear against the inner ends of thespringblocks K L, and and the arms c' of the said springs are arrangedto bear against the ends of the collar q of spring' H. From this itfollows that the springs N,which are obviously strong and durable, willserve to eiieiently cushion lateral thrust and pull imposed in eitherdirection on the hub.

It will be appreciated from the foregoing that notwithstanding my novelhub is calculated to prevent the transmission of shock and jar to theframes and bodies of vehicles and machines of various kindsnsuch astraction-engines, threshers, &e.-the said hub is strong and durable andembodies no delicate parts, such as are liableto get out of order aftera short period of use.

With a view of preventing injury to any of the parts of the hub when thecasing B has a great weight imposed upon it I prefer to provide a rubberannulus T, which is suitably secured on the outer end of thespring-block K. The said rubber annulus will in the event of the casingB being greatly depressed on the axle A, be engaged by the intersectionof the casing and will cushion said section in an eiiicient manner.

With the exception of the annulus C, the bellows D, and the annulus Tall the parts of my improved hub are preferably of steel.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in my improved hub with aview of imparting a definite understanding of the improved construction.I do not desire, however, to be understood as coniining myself to suchspecific construction and relative arrangement of parts, as such changesor modifications may be made in practice as fairly fall within the scopeof my invention as claimed.

Having described my invention, what l claim, and desire to seeul'e byLetters Patent, is-

1. In a wheel-hub, the combination oi an axle, a casing loosely mountedon and movable up and down and endwise with respect to the axle, aweight-sustaining coiled spring connected to and surrounding the axleand interposed between the same and the casing, and springs interposedbetween the axle and the casing and arranged to cushion endwisemovement-of the same.

2. In a wheel-hub, the combination of an axle, a casing loosely mountedon and movable up and down and endwise with respect to the axle, aweight-sustaining coiled spring connected to and surrounding' the axleand interposed between the same and the casing, springs interposedbetween the axle and the easing and arranged to cushion endwise movementoi the same, an annulus surrounding the axle; and a bellows connectingthe annulus and the casing and arranged at one end oi the latter.

8. In a wheel-hub, the combination oi an axle, a easing loosely mountedon the axle, a coiled spring connected to and surrounding the axle andinterposed between the same and the casing, sets of springs disposed atopposite sides of the coiled spring, and connected to the axle andinterposed between the axle and the casing, and springs mounted on theaxle and interposed between the connection o1 the coiled spring and theconnections of the said sets of springs.

4. In a wheel-hub, the combination oi? an axle, a casing loosely mountedon the axle, an annular shell contained in the casing and havinginwardly-directed lugs on its edges, one or more circumferential seriesoi' antiiriction devices interposed between the perimeter of the shelland the casing, a coiled spring connected to the axle and interposedbetween the same and the shell, and having its outer portion disposedbetween the lugs of the shell, blocks mounted on the axle at oppositesides of the coiled spring, springs connected at their inner ends tosaid blocks and bearing at their outer ends against the casing, andsprings mounted on the axle and interposed between the inner portion ofthe coiled spring and the spring-blocks.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

CHARLES C. BRABANT.
